Lenovo ThinkPad notebooks have always been known for their excellent keyboards and build quality; with the X series possibly being the cream of the ThinkPad crop. Consequently, Lenovo is adding another model to their ultraportable line, this time the X220. According to a couple PDF’s available on Lenovo’s online store, the X220 will be available in both tablet and notebook formats.

With regards to the X220 notebook, it will be powered by a wide range of Sandy Bridge Intel processors (up to a 2.7GHz Core i7-2620QM ), up to 8GB of DDR3 RAM, Integrated Intel HD graphics, and an optional USB 3.0 port. However, what really makes the X220 an intriguing choice is the optional IPS (In Plane Switching) version of the 12.5” (1366x768 pixel)display, the optional 160GB SSD and some very long battery runtimes. According to the PDF, the X220 laptop will be able to crank out a full 15 hours of runtime courtesy of the internal 9 Cell battery. And as if that wasn’t long enough, users on the go will be able to purchase a slim external battery pack that gives you almost a full day of use (23 hours).

As for the X220 tablet, while it doesn’t have as much bang as the laptop model, it features an appealing skillset nonetheless. According to the PDF, the tablet will also feature Sandy Bridge processors, although the options are less than the notebook model. Other than that, the X220 tablet will include a 12.5” IPS (300NIT) display with optional Gorilla Glass, up to a 160GB SSD, and the same integrated graphics as the notebook model. Unfortunately, the tablet will not have the same battery life as the notebook, although it does manage 18 hours with the external battery and 9 hours without.

All in all, the Lenovo X220 Tablet and Notebook versions feature some solid specs; with the IPS display and extended battery life being some premium options. Unfortunately, there is no word of pricing and release date, although the PDF documents might mean we end up hearing something soon.
